"Always turn on the Nylon sign, make sure that the newest issue is out and make sure that you are constantly smiling," Nylon receptionist Lauren Adler, whom Radcliffe was replacing for about an hour, advised in a hidden-camera video.

"It's going to be rough," Radcliffe quipped.

The "Young Americans" star (yes, he's been in other movies besides HP) then took his seat at reception and just went with it.

Lots of staffers walked by without noticing. One staffer stopped, stared and told him he had great hair. And one took a fan photo (but not without feeling awkward about it at first).

One finally had the courage to ask what we were all wondering.

"What are you doing here?"

"I'm preparing for my next role at the moment," he said. "It's already proving to be the hardest thing I've ever done. Like, the hardest thing I've ever done." (We're hoping that he's joking because we haven't seen any actual work being done.)

However, as the video progresses, Radcliffe gets increasingly bombarded with typical receptionist requests. He's asked to hold something for delivery. He's asked to call people for meetings. He's asked to find people he doesn't even know. He's basically barraged by people to the point that he just hopes no one else comes near the front door.

Then Joe Jonas, of the Jonas Brothers fame, walks in. Acting as if he doesn't recognize Radcliffe, Jonas asks if he's from the England office. He then asks Radcliffe to call someone, who's not answering. Then he asks him to physically go get the person.

When Radcliffe runs off camera, Jonas quips, "This new guy sucks."

We secretly hoped that Radcliffe would bust out a wand and an Expecto Patronum spell like the old days—but no such luck.
